The mile is an English unit of length of linear measure equal to 5,280 feet, or 1,760 yards, and standardised as exactly 1,609.344 metres by international agreement in 1959.

With qualifiers, "mile" is also used to describe or translate a wide range of units derived from or roughly equivalent to the Roman mile, such as the nautical mile (now 1.852 km exactly), the Italian mile (roughly 1.852 km), and the Chinese mile (now 500 m exactly). The Romans divided their mile into 5,000 feet but the greater importance of furlongs in pre-modern England meant that the statute mile was made equivalent to 5,280 feet or 1,760 yards in 1593. This form of the mile then spread to the British-colonized nations who continue to employ the mile. The US Geological Survey now employs the metre for official purposes but legacy data from its 1927 geodetic datum has meant that a separate US survey mile (6336/3937 km) continues to see some use. While most countries replaced the mile with the kilometre when switching to the International System of Units, the international mile continues to be used in some countries, such as Liberia, Myanmar, the United Kingdom, the United States, and a number of countries with less than a million inhabitants, most of which are UK or US territories, or have close historical ties with the UK or US.

The mile was usually abbreviated m. in the past but is now sometimes written as mi to avoid confusion with the SI metre; road signs in the United Kingdom continue to use m as the abbreviation for mile. Derived units such as miles per hour and miles per gallon, however, continue to be universally abbreviated as mph, mpg, and so on.


The modern English word mile derives from Middle English myl and Old English mīl, which was cognate with all other Germanic terms for "miles". These derived from apocopated forms of the Latin mīlia or mīllia, the plural of mīle or mīlle,[n 1] literally "thousand" but used as a clipped form of mīlle passus or passuum, the Roman mile of one thousand paces.[1]

The present international mile is usually what is understood by the unqualified term "mile". When this distance needs to be distinguished from the nautical mile, the international mile may also be described as a "land mile" or "statute mile".[2] In British English, the "statute mile" may refer to the present international miles or to any other form of English mile since the 1593 Act of Parliament which set it as a distance of 1,760 yards. Under American law, however, the "statute mile" refers to the US survey mile.[3] Foreign and historical units translated into English as miles usually employ a qualifier to describe the kind of mile being used but this may be omitted if it is obvious from the context, such as a discussion of the 2nd-century Antonine Itinerary describing its distances in terms of "miles" rather than "Roman miles".

The mile has been variously abbreviated—with and without a trailing period—as m, M, ml, and mi. The American National Institute of Standards and Technology now uses and recommends mi in order to avoid confusion with the SI metre (m) and millilitre (mL).[4] Derived units such as miles per hour and miles per gallon, however, continue to be abbreviated in the United States, United Kingdom, and Canada as mph, mpg, etc. rather than mi/h or mi/gal. The BBC style holds that "There is no acceptable abbreviation for ‘miles’" and so it should be spelt out when used in describing areas.[5]

Historical miles

The remains of the Golden Milestone, the zero mile marker of the Roman road network, in the Roman Forum

Roman mile

The Roman mile (mille passus, lit. "thousand-pace"; abbr. m.p.; also mille passuum[n 2] and mille) consisted of a thousand paces as measured by every other step—as in the total distance of the left foot hitting the ground 1,000 times. The ancient Romans, marching their armies through uncharted territory, would often push a carved stick in the ground after each 1000 paces. Well-fed and harshly driven Roman legionaries in good weather thus created longer miles. The distance was indirectly standardised by Agrippa's establishment of a standard Roman foot (Agrippa's own) in 29 BC,[7] and the definition of a pace as 5 feet. An Imperial Roman mile thus denoted 5,000 Roman feet. Surveyors and specialized equipment such as the decempeda and dioptra then spread its use.[8] In modern times, Agrippa's Imperial Roman mile was empirically estimated to have been about 1,481 metres (4,851 English feet or 1,617 English yards) in length.[9] In Hellenic areas of the Empire, the Roman mile (Greek: μίλιον, mílion) was used beside the native Greek units as equivalent to 8 stadia of 600 Greek feet. The mílion continued to be used as a Byzantine unit and was also used as the name of the zero mile marker for the Byzantine Empire, the Milion, located at the head of the Mese near Hagia Sophia.

The Roman mile also spread throughout Europe, with its local variations giving rise to the different units below.

Also arising from the Roman mile is the 'milestone'. All roads radiated out from the Roman Forum throughout the Empire – 50,000 miles of stone-paved roads. At every mile was placed a shaped stone, on which was carved a Roman numeral, indicating the number of miles from the center of Rome – the Forum. Hence, one always knew how far he or she was from Rome.

Italian mile

The Italian mile (miglio, pl. miglia) was traditionally considered a direct continuation of the Roman mile, equal to 1000 paces,[10] although its absolute value over time or between regions could vary greatly.[11] It was often used in international contexts from the Middle Ages into the 17th century[10] and is thus also known as the "geographical mile",[12] although the geographical mile is now a separate standard unit.

Arabic mile

Main article: Arabic mile

The Arabic mile (الميل, al-mīl) was not the common Arabic unit of length; instead, Arabs and Persians traditionally used the longer parasang or "Arabic league". The Arabic mile was, however, used by medieval geographers and scientists and constituted a kind of precursor to the nautical or geographical mile. It extended the Roman mile to fit an astronomical approximation of 1 arcminute of latitude measured directly north-and-south along a meridian. Although the precise value of the approximation remains disputed, it was somewhere between 1.8 and 2.0 km.

British and Irish miles

English mile

See also: yard

The "old English mile" of the medieval and early modern periods varied but seems to have measured about 1.3 international miles (1.9 km).[13] The English long continued the Roman computations of the mile as 5000 feet, 1000 paces, or 8 longer divisions, which they equated with their "furrow's length" or furlong.[14]

The origins of English units are "extremely vague and uncertain",[15] but seem to have been a combination of the Roman system with native British and Germanic systems both derived from multiples of the barleycorn.[n 3] Probably by the reign of Edgar in the 10th century, the nominal prototype physical standard of English length was an arm-length iron bar (a yardstick) held by the king at Winchester;[16][18] the foot was then one-third of its length. Henry I was said to have made a new standard in 1101 based on his own arm.[15] Following the issuance of Magna Carta, the barons of Parliament directed John and his son to keep the king's standard measure (Mensura Domini Regis) and weight at the Exchequer,[15] which thereafter verified local standards until its abolishment in the 19th century. New brass standards are known to have been constructed under Henry VII and Elizabeth I.[19]

Arnold's c.1500 Customs of London recorded a mile shorter than previous ones, coming to 0.947 international miles or 1.524 km.[14]

The English statute mile was established by a Weights and Measures Act of Parliament in 1593 during the reign of Queen Elizabeth I. The act on the Composition of Yards and Perches had shortened the length of the foot and its associated measures, causing the two methods of determining the mile to diverge.[20] Owing to the importance of the surveyor's rod in deeds and surveying undertaken under Henry VIII,[21] decreasing the length of the rod by 111 would have amounted to a significant tax increase. Parliament instead opted to maintain the mile of 8 furlongs (which were derived from the rod) and to increase the number of feet per mile from the old Roman value.[22] The applicable passage of the statute reads: "A Mile shall contain eight Furlongs, every Furlong forty Poles,[n 4] and every Pole shall contain sixteen Foot and an half."[23] The statute mile therefore contained 5,280 feet or 1,760 yards.[14] The distance was not uniformly adopted. Robert Morden had multiple scales on his 17th-century maps which included continuing local values: his map of Hampshire, for example, bore two different "miles" with a ratio of 1:1.23[25] and his map of Dorset had three scales with a ratio of 1:1.23:1.41.[26] In both cases, the traditional local units remained longer than the statute mile.

Welsh mile

The Welsh mile (milltir or milldir) was 3 miles and 1470 yards long (6.17 km). It comprised 9000 paces (cam), each of 3 Welsh feet (troedfedd) of 9 inches,[27] usually reckoned as equivalent to the English inch. Along with other Welsh units, it was said to have been codified under Dyfnwal the Bald and Silent and retained unchanged by Hywel the Good.[28] Along with other Welsh units, it was discontinued following the conquest of Wales by the English under Edward I in the 13th century.

Scots mile

Edinburgh's "Royal Mile"—running from the castle to Holyrood Abbey—is roughly a Scots mile long.[29]

The Scots mile is longer than the English mile,[30] as mentioned by Robert Burns in the first verse of his poem "Tam o' Shanter". It comprised 8 (Scots) furlongs divided into 320 falls or faws (Scots rods).[31] It varied from place to place but the most accepted equivalencies are 1,976 Imperial yards or 1.81 km, i.e., 1.086 United States statute miles.[14][32]

It was legally abolished three times: first by a 1685 act of the Scottish Parliament,[33] again by the 1707 Treaty of Union with England,[34] and finally by the Weights and Measures Act 1824.[30] It had continued in use as a customary unit through the 18th century but had become obsolete by its final abolition.

Irish mile

Main article: Irish mile

The Irish mile (míle or míle Gaelach) measured 2240 yards: approximately 1.27 statute miles or 2.048 kilometres.[35] It was used in Ireland from the 16th century plantations until the 19th century, with residual use into the 20th century. The units were based on "English measure" but used a linear perch measuring 7 yards (6.4 m) as opposed to the English rod of 5.5 yards (5.0 m).

International mile

The international mile is precisely equal to 1.609344 km (or 25146/15625 km as a fraction).[40] It was established as part of the 1959 international yard and pound agreement reached by the United States, the United Kingdom, Canada, Australia, New Zealand, and South Africa,[42] which resolved small but measurable differences that had arisen from separate physical standards each country had maintained for the yard.[43] As with the earlier statute mile, it continues to comprise 1,760 yards or 5,280 feet.

The old Imperial value of the yard was used in converting measurements to metric values in India in a 1976 Act of the Indian Parliament.[44] However, the current National Topographic Database of the Survey of India is based on the metric WGS-84 datum,[45] which is also used by the Global Positioning System.

The difference from the previous standards was 2 ppm, or about 3.2 millimeters (18 inch) per mile. The U.S. standard was slightly longer and the old Imperial standards had been slightly shorter than the international mile. When the international mile was introduced in English-speaking countries, the basic geodetic datum in America was the North American Datum of 1927 (NAD27). This had been constructed by triangulation based on the definition of the foot in the Mendenhall Order of 1893, with 1 foot = 1200/3937 metres and the definition was retained for data derived from NAD27, but renamed the U.S. survey foot to distinguish it from the international foot.[46][n 5]

The exact length of the land mile varied slightly among English-speaking countries until the international yard and pound agreement in 1959 established the yard as exactly 0.9144 metres, giving a mile exactly 1,609.344 metres. The U.S. adopted this international mile for most purposes, but retained the pre-1959 mile for some land-survey data, terming it the U. S. survey mile. In the United States, statute mile normally refers to the survey mile,[47] about 3.219 mm (18 inch) longer than the international mile (the international mile is exactly 0.0002% less than the U.S. survey mile).

While most countries replaced the mile with the kilometre when switching to the International System of Units, the international mile continues to be used in some countries such as Liberia, Myanmar,[48] the United Kingdom[49] and the United States.[50] It is furthermore used in a number of countries with vastly less than a million inhabitants, most of which are UK or US territories, or have close historical ties with the UK or US: American Samoa,[51] Bahamas,[52] Belize,[53] British Virgin Islands,[54] Cayman Islands,[55] Dominica,[55] Falkland Islands,[56] Grenada,[57] Guam,[58] The N. Mariana Islands,[59] Samoa,[60] St. Lucia,[61] St. Vincent & The Grenadines,[62] St. Helena,[63] St. Kitts & Nevis,[64] the Turks & Caicos Islands,[65] and the U.S. Virgin Islands.[66] The mile is even encountered in Canada, though this is predominantly in rail transport and horse racing, as the roadways have been metricated since 1977.[67][68][69][70]

US survey mile

The U.S. survey mile is 5,280 survey feet, or about 1609.347218694 metres.[71] In the U.S., statute mile formally refers to the survey mile,[3] but for most purposes, the difference between the survey mile and the international mile is insignificant—one international mile is 0.999998 U.S. survey miles—so statute mile can be used for either. But in some cases, such as in the U.S. State Plane Coordinate Systems (SPCSs), which can stretch over hundreds of miles,[72] the accumulated difference can be significant, so it is important to note that the reference is to the U.S. survey mile.

The US redefined its yard in 1893, but this resulted in U.S. and Imperial measures of distance having very slightly different lengths.

The North American Datum of 1983 (NAD83), which replaced the NAD27, is defined in meters. State Plane Coordinate Systems were then updated, but the National Geodetic Survey left individual states to decide which (if any) definition of the foot they would use. All State Plane Coordinate Systems are defined in meters, and 42 of the 50 states only use the metre-based State Plane Coordinate Systems. However, eight states also have State Plane Coordinate Systems defined in feet, seven of them in U.S. Survey feet and one in international feet.[72] State legislation in the U.S. is important for determining which conversion factor from the metric datum is to be used for land surveying and real estate transactions, even though the difference (2 ppm) is hardly significant, given the precision of normal surveying measurements over short distances (usually much less than a mile). Twenty-four states have legislated that surveying measures be based on the U.S. survey foot, eight have legislated that they be based on the international foot, and eighteen have not specified which conversion factor to use.[72]

Nautical mile

On the utility of the nautical mile.
Each circle shown is a great circle—the analog of a line in spherical trigonometry—and hence the shortest path connecting two points on the globular surface. Meridians are great circles that pass through the poles.
Main article: Nautical mile

The nautical mile was originally defined as one minute of arc along a meridian of the Earth.[73] Navigators use dividers to step off the distance between two points on the navigational chart, then place the open dividers against the minutes-of-latitude scale at the edge of the chart, and read off the distance in nautical miles.[74] The Earth is not perfectly spherical but an oblate spheroid, so the length of a minute of latitude increases by 1% from the equator to the poles. Using the WGS84 ellipsoid, the commonly accepted Earth model for many purposes today, one minute of latitude at the WGS84 equator is 6,046 feet and at the poles is 6,107.5 feet. The average is about 6,076 feet (about 1,852 metres or 1.15 statute miles).

In the United States the nautical mile was defined in the 19th century as 6,080.2 feet (1,853.249 m), whereas in the United Kingdom, the Admiralty nautical mile was defined as 6,080 feet (1,853.184 m) and was about one minute of latitude in the latitudes of the south of the UK. Other nations had different definitions of the nautical mile, but it is now internationally defined to be exactly 1,852 metres (6,076.11548556 feet).[75]

Related nautical units

The nautical mile per hour is known as the knot. Nautical miles and knots are almost universally used for aeronautical and maritime navigation, because of their relationship with degrees and minutes of latitude and the convenience of using the latitude scale on a map for distance measuring.

The data mile is used in radar-related subjects and is equal to 6,000 feet (1.8288 kilometres).[76] The radar mile is a unit of time (in the same way that the light year is a unit of distance), equal to the time required for a radar pulse to travel a distance of two miles (one mile each way). Thus, the radar statute mile is 10.8 μs and the radar nautical mile is 12.4 μs.[77]

Geographical mile

Main article: Geographical mile

The geographical mile is based upon the length of a meridian of latitude. The German geographical mile (geographische Meile) was previously 115° of latitude (7.4127 km).[78]

Grid system

Cities in the continental United States often have streets laid out by miles. Detroit, Indianapolis, Chicago, Phoenix, Philadelphia, Las Vegas, Los Angeles, and Miami, are several examples. Typically the largest streets are about a mile apart, with others at smaller intervals. In the Manhattan borough of New York City "streets" are close to 20 per mile, while the major numbered "avenues" are about six per mile. (Centerline to centerline, 42nd Street to 22nd Street is supposed to be 5250 feet while 42nd Street to 62nd Street is supposed to be 5276 ft 8 in.)

Metric mile

Main article: Metric mile

The informal term "metric mile" is used in sports such as track and field athletics and speed skating to denote a distance of 1,500 metres (4,921 ft). In United States high-school competition, the term is sometimes used for a race of 1,600 metres (5,249 ft).[79]

Scandinavian mile

Main article: Scandinavian mile

The Scandinavian mile (mil) remains in common use in Norway and Sweden, where it has meant precisely 10 km since metrication occurred in 1889.[36] It is used in informal situations and in measurements of fuel consumption, which are often given as litres per mil. In formal situations (such as official road signs) and where confusion may occur with international miles, it is avoided in favour of kilometres.

The Swedish mile formerly varied by province from 6–14.485 km. It was standardised in 1649 as 36,000 Swedish feet or 10.687 km.[36] Prior to metrication, the Norwegian mile had been 11.298 km. (The traditional Finnish peninkulma was translated as mil in Swedish and also set equal to 10 km during metrication in 1887, but is much less commonly used.)
